Contiguous Local Authorities Groups (CLAGs)
 Not unique to Western Australia:
 Queensland (between LG’s only).
 NT – State program around Darwin
 What is unique in WA:
 the partnership with DoH; and
 Funding provided to LG by DoH for mosquito
management.
Contiguous Local Authorities Groups (CLAGs)
 CLAG funding scheme initiated in 1990 to assist
Local Governments in with mosquito control and
management.
 Recognition of difficulties in managing
mosquitoes when LG’s worked alone.
 Mosquitoes cross LG boundaries!
 Treatments in one LG may be ineffective if
mosquitoes disperse from outside the LG.
Muddy Lakes – An example




Remnant of larger Minninup Lake system
Brackish non-tidal swamp
Extensive Aedes camptorhynchus breeding
Acid sulfate soils
 Fewer aquatic competitors
 Reduced efficacy of mosquito control chemicals
 Western Grey Kangaroos in surrounding
bushland
Muddy Lakes, Capel (2011-12)
High attack rates in semi rural
settings in SW – ‘high risk’
persists over larger area
RRV case
Non-industrial dwelling
Shire of Capel – Mark/Recapture study
Pre-requisites for a CLAG in SW and Perth:
 a public health risk from mosquitoes (locally
acquired cases of mosquito-borne disease);
 a knowledge of mosquito breeding sites within
each of the participating Local Governments;
 an appropriate Mosquito Management Plan
(MMP); and/or
 a recognised common mosquito problem across
LG borders.
To form a CLAG elsewhere in WA:
 Pre-requisites for the formation of a single LG
CLAG elsewhere:
 a public health risk from mosquitoes (locally
acquired cases of mosquito-borne disease);
 a knowledge of mosquito breeding sites within the
LG area; and
 an appropriate Mosquito Management Plan
(MMP).
Current CLAGs in Western Australia
 11 CLAGs in WA comprising 26 LGs
 Northern Western Australia – 4 CLAGs
Derby/West
Kimberley
Port Hedland
Roebourne
Carnarvon
Current CLAGs in Western Australia
 Peel
 Leschenault
 Geographe
Current CLAGs in Western Australia
 WannerooJoondalup
 Subiaco-Nedlands
 East Swan River
 Swan and Canning
Rivers
CLAG Memorandum of Understanding (MoU)
 Recognises formation of
CLAG;
 CLAG function;
 Responsibility of Key
Players;
 Signed and approved by:
 LG CEO’s and
 Director – EH
CLAG – Terms of Reference (ToR)
 CLAG functions
 Chairperson
 Secretary
 CLAG Meetings
 Decision making
processes
 Funding and reporting
Benefits of forming a CLAG in WA:
 CLAG funding includes:
 100% cost of helicopter for health driven aerial
larviciding applications in SW only;
 50% cost of larvicides to control breeding in
waterways;
 50% cost of adulticides for CLAGs in the north where
larviciding is not logistically feasible;
 funding for basic earthworks (after environmental
approvals are completed); and
 funding towards media campaigns and strategies.
Further DoH Contribution to CLAGs
 Guidance and advice throughout the mosquito
season at regular CLAG meetings:
 Updated disease stats for your region;
 Weather predictions and forecasts;
• Help with:
 Mosquito Management Plans;
 ground surveillance activities;
 advice on treatment options;
 advice on trapping, equipment use;
 training and development of staff; and
 other advice on LG specific problems.
CLAGs = Integrated approach to Mosquito
Management
 Combines local knowledge, monitoring and
control activities with scientific/technical input;
 (Collective State and LG knowledge/expertise);
 Regional approach to mosquito management;
 Sharing of resources by LG’s;
 Equipment; Media campaigns; Staff; Training and
development; research etc
