ROTTNEST ISLAND MANAGEMENT PLAN
388. Hon LYNN MacLAREN to the
parliamentary secretary representing the Minister for Tourism:
(1) Does the
Rottnest Island Management Plan 2014–19 include a vulnerability
assessment for the whole of the Rottnest Island coastline?
(2) How much
infrastructure is in the transition zone; the area of the coastal zone most
likely to be vulnerable to coastal erosion, saltwater inundation and storm
surge flooding?
(3) Which of
the accommodation units and tourist infrastructure in the plan are on low-lying
sandy landforms?
(4) Has the plan included the results from the
Intergovernmental Panel on Climate Change's ''Fifth Assessment
Report'', which concluded ''the rate of sea level rise will very
likely exceed that observed from 1971 to 2010 due to increased ocean warming
and increased loss of mass from glaciers and ice sheets''?
(5) Which
agencies and departments will be responsible for repairs to and replacement of
infrastructure damaged by coastal erosion, saltwater inundation and storm surge
flooding?
(6) How has
the Rottnest Island Management Plan 2014–19 reflected the precautionary
principle, that the avoidance of fixture risk is the most cost effective
adaptation in response to sea level rise?

I thank the honourable member for some notice of the question.
(1) No;
however, the Rottnest Island Management Plan 2014–19 took into account
the findings of a report on the potential effects of climate change on Rottnest
Island prepared in June 2011 titled ''Rottnest Island Preliminary
Climate Change Vulnerability Assessment'' and that identified high-risk
areas and infrastructure.
(2) The
Rottnest Island master plan is conceptual at this stage. Any proposed
developments will be subject to geological surveys, as well as the Rottnest
Island Authority's development planning guidelines.
(3) Refer to
(2).
(4) The RIMP
and Rottnest Island master plan were prepared before the information from the
IPCC's ''Fifth Assessment Report'' was released.
(5) It is the
responsibility of the Rottnest Island Authority, with the exception of the
jetties, which are vested in the Department of Transport.
