Marine tourism and recreational use of the marine environment
Nature-based tourism is growing in popularity (Hardiman and Burgin 2010). The potential
benefits of marine tourism include a greater appreciation of local marine biota, increased
awareness of conservation actions and greater opportunity for conservation initiatives driven by
the economic potential of ecotourism. Nonetheless, the impacts of marine tourism on natural
systems can be substantial, which is why tourism was highlighted as a threat to marine
biodiversity in the NRM Ministerial Council Marine Biodiversity Decline Report (2008).
Tourism activities adjacent to NSW Marine Parks have been profiled in part in a series of
reports to NSW Government agencies (e.g., CARE 2005, 2006, NSW Marine Parks Authority
2006, 2006, Arche Consulting 2010a, b, c, d, e, f, g). These reports have mostly focused on the
influence of marine protected areas on regional economies because (i) marine activities are a
driver of visitation to Local Government Areas (LGAs) adjacent to NSW marine parks and (ii)
over 30% of businesses in these areas have an association with the tourism industry (Arche
Consulting 2010a). Commercial tourism businesses operating in NSW marine parks include
beach equipment hire, boat hire, charter fishing, general charters, dive operators, marine
mammal watching, ferry services, filming, photography, houseboat hire, jetski hire, kayaking,
parasailing, surf schools and thrill rides.
The majority of tourists visiting LGAs adjacent to mainland marine parks in NSW are from the
domestic market, with less than 5% being international for all parks except Cape Byron Marine
Park with 13%. Across all mainland NSW marine parks, going to the beach was the most
popular activity for domestic tourists followed by eating out, visiting friends and relatives,
walking or driving around, shopping and going to pubs, clubs, etc. (Arche Consulting 2010a).
For international tourists, going to the beach was also the most popular activity with national
parks and dolphin watching being important at some locations (Arche Consulting 2010a).
Understanding tourism is of crucial importance to effective management of marine parks, in
terms of (i) establishing the benefits and cost of marine parks to regional economies reliant on
tourism, (ii) targeting promotional, educational and advisory material to maximize appreciation of
the marine environment and voluntary compliance, (iii) prioritizing enforcement activities to
compensate for seasonal changes in visitation and (iv) minimizing conflict over access to marine
resources among different stakeholder groups.
The national focus on marine tourism as key threat to marine biodiversity probably stems from
iconic marine parks with sensitive habitats located in relatively remote areas. For example,
tourism impacts are of great concern for the 7% of the Great Barrier Reef Marine Park that
receives 85% of the 1.6 million tourists per year (Harriott 2002). In contrast, in the many
population centres on the NSW coast the impacts on marine biodiversity from local coastal
populations can outweigh those of tourists when they participate in similar activities (e.g. beach
going, fishing, surfing, etc.). With perhaps the exception of Lord Howe Island and several other
peak tourist destinations (e.g. Julian Rocks in Cape Byron Marine Park), it is more useful to
consider threats to marine biodiversity as the cumulative impacts of tourists and locals in NSW,
rather than separating these groups.

Users of marine and estuarine ecosystems in NSW participate in a range of extractive (e.g.,
charter fishing, shell collecting, etc.) and non-extractive activities (e.g., sailing, surfing,
swimming, etc.). Read and West (2010) identified 76 permitted activity types carried out in
NSW marine parks that have potential to impact biodiversity. Twenty of these were nonextractive activities that were divided into broad categories, including boating, marine mammal
watching, scuba diving, airplanes, artificial reefs, dog walking, fish feeding, education programs
and organized events (non-fishing). Low-impact activities, such as swimming or beach walking,
were not included. The 20 activities risk-assessed by Read and West (2010) fit well with those
indicated in community and visitor recreational use questionnaires and a random phone survey
of residents adjacent to NSW marine parks (e.g., NSW Marine Parks Authority 2003). As
extractive resource use is covered by other background documents, this following information
will focus on key non-extractive activities carried out in NSW marine parks.
Recent reviews of the impacts of tourism and recreational use of marine systems by Ormsby et
al. (2004), Davenport and Davenport (2006), and Hardiman and Burgin (2010) provide useful
summaries of the primary scientific literature around this topic. In particular, Hardiman and
Burgin’s (2010) review contains many references from Australia and NSW. Rather than
providing a similar broad literature review, the following background information will highlight
threats and introduce literature important for management of non-extractive resources use in
NSW marine parks.
General low-impact activities:
Non-extractive foreshore-based activities (e.g., swimming, exercising, beach pursuits, surfing,
etc.) represent the most popular pastimes in the NSW marine parks. In general, these activities
pose little threat to biodiversity and thus have low priority in conservation management plans.
However, Illegal littering or wildlife disturbance during foreshore activities can have lasting
impacts. Similarly, excessive trampling of intertidal algae, plants and animals can also cause
substantial impacts to some intertidal habitats (e.g., saltmarsh, NSW Department of
Environment and Climate Change 2008, mangroves, Ross 2006 or rocky shores, Keough and
Quinn 1998). Interactions between domestic animals and wildlife (e.g., dogs, birds and seals)
are also of concern because they can impact the breeding success of threatened shorebirds or
facilitate interspecies disease transmission (e.g., see Australian Wildlife Health Network 2011
for review of morbilliviruses and Australian seals). Fish feeding also needs to be cautiously
managed to minimize impacts to biota and visitors (Brookhouse 2011).
For NSW marine parks, low-impact activities are generally managed on a case by case basis to
ensure the objects of Marine Parks Act (1997) are not compromised. When low-impact
activities are commercial ventures (e.g. kayak tours) or organized events (e.g. triathlons) they
are managed through a NSW Marine Parks Authority’s permitting process. In general,
management actions addressing low- impact activities on the foreshore are carried out in
collaboration with local government or national park rangers.

Visitor infrastructure:
Substantial foreshore development is required to facilitate commercial and recreational activities
in marine systems. This can include a variety of infrastructure, such as harbours, boat ramps,
jetties, retaining walls, groynes, marinas, slipways, pump out stations, shark mesh nets, artificial
reefs, etc. Installation of these structures can be associated with habitat destruction (e.g., loss
of mangroves, seagrasses, salt marshes, etc), changes in habitat structure and complexity,
alterations of biotic assemblages and in the cases of marinas, increased opportunity for invasion
and pollution. Furthermore, many of these structures also alter abiotic conditions, including
hydrodynamics and sediment dynamics with further flow on effects to structure and function of
ecosystems.
One particular concern for Jervis Bay Marine Park has been the impact of swing moorings on
seagrass (Posidonia australis) beds. Consequently, two projects have been undertaken to
investigate (i) the impacts of moorings on seagrass habitats (Crawford 2003) and (ii) the cost
and benefits of seagrass-friendly moorings (Demers 2011).
Local governments, the Land and property Management Authority, NSW Maritime and NSW
Marine Parks Authority all have vested and inter-related management responsibilities for the
foreshore of mainland marine parks in NSW. Foreshore management plans are often adopted
to ensure coordination among relevant agencies (e.g., Port Stephens Foreshore Management
Plan, Umwelt 2009).
Boating:
Approximately 33% of Australia’s boating activity occurs in NSW waters (National Maritime
Safety Committee 2010). The numbers of boating licenses, vessel registrations and moorings
have been steadily increasing over the last decade in NSW (NSW Maritime 2010). Despite this,
if regulations and guidelines are followed then boating represents a limited threat to marine
biodiversity in NSW. If not managed appropriately, however, boating activities can impact
biodiversity through careless anchoring, wake-induced shoreline erosion, toxic anti-fouling paint,
propeller damage to aquatic vegetation, boat strikes to wildlife, excessive noise or illegal
discharge of pollutants (Davenport and Davenport 2006). Probably the most significant threat
from boating is the translocation of invasive species (Hardiman and Burgin 2010). The
expanding cruise ship industry is also cause for concern (Davenport and Davenport 2006), as
the capacity of the largest ships now exceeds 5000 people. Cruise visitation to NSW marine
parks has been slowly increasing and may require more consideration in future operational
plans.
Boating activities are appropriately regulated in NSW to minimize threats to marine biodiversity.
Principally, NSW Maritime is responsible for the management of boating activities and their
impacts. However, NSW marine parks have specific legislation to ensure responsible anchoring
and that heavily fouled or abandoned vessels do not impact on natural values. A Memorandum
of Understanding between NSW Maritime and NSW Marine Park Authority signed in 2010
clarifies the responsibilities of the two organizations.
There has been concern about the potential negative impacts of fast moving boats on dolphin
populations in NSW marine parks. Research in Jervis Bay and Port Stephens–Great Lakes
4
marine parks suggests that fast moving boats do not have substantial impacts on dolphin
surface behaviour (Lemon et al. 2005, Stechenruter et al. 2011).
Vehicles on beaches:
The use of 4WDs on beaches is becoming increasingly popular in Australia (Hardiman and
Burgin 2010). Environmental impacts for this activity can include degradation of dune
vegetation, displacement of birds and reduced survival rate of newly hatched turtles, as well as
impacts to ghost crabs, pipis and other biota. Because the potential for impacts to beach fauna
from 4WDing was relatively unknown, the NSW Marine Parks Authority has been involved in
several studies addressing this knowledge gap (Bell 2005, Sheppard et al. 2009).
Scuba diving:
Scuba diving is a key activity for promoting awareness and appreciation for marine
environments and is popular within NSW marine parks. Julian Rocks in Cape Byron Marine
Park, for example, can have as many as 35000 divers per year, contributing an estimated $2.8
million p.a. to the local community (NSW Marine Parks Authority 2003). The physical impact of
divers on corals has been well documented in the scientific literature, which is a key
consideration for marine parks in northern NSW and at Lord Howe Island. Substantial work has
been also done on diver interactions with grey nurse sharks in NSW (see Grey Nurse Shark
background document). Researchers from Jervis Bay Marine Park have also undertaken
studies investigating (i) interactions between fishers and divers (Lynch et al. 2004) and (ii) the
impacts of “shark shields” on elasmobranch behaviour (Broad et al. 2010).
Wildlife watching:
Wildlife observation is popular activity along the NSW coast. In particular, whale and dolphin
watching represents a lucrative commercial activity in NSW waters. For example, Port
Stephens–Great Lakes Marine Park supports up to 250,000 passengers per year on dedicated
dolphin watching trips generating ca. $5 million pa in gross revenue (NSW Marine Parks
Authority 2010). Intensive observation of marine mammals, such as whales, dolphins and
seals, has the potential to alter their behaviour if appropriate consideration is not given (e.g.,
Stamation et al. 2010). To address this, the Australian National Guidelines for Whale and
Dolphin Watching (Department of Environment and Heritage 2005) is applied in NSW marine
parks through regulations within the National Parks and Wildlife Act.
