This paper identifies a number of the key elements that underpinned th
e success of Australia's public health response to minimizing the spre
ad of HIV, It is argued that one major factor was the high level of co
llaboration between health care professionals and ''affected'' communi
ties, such as injecting drug users, sex industry workers and gay men,
This collaboration allowed for the negotiation, development and implem
entation of the range of innovative HIV initiatives that were ultimate
ly responsible for keeping HIV in the injecting drug use and sex indus
try to low levels, Despite the central role played by injecting drug u
sers and their peer based organizations, the significance of their act
ivities has gone largely unacknowledged by senior health bureaucrats a
nd politicians, As a consequence, advice from injecting drug users and
their peer-based organizations on the current hepatitis C epidemic ha
s been largely ignored, Instead of learning from Australia's HIV exper
ience and involving these groups in consultation and advisory roles, t
he Federal Government has reverted to accepting advice from only estab
lished mainstream organizations. It is argued that the success of infe
ction control outside mainstream communities, such as among injecting
drug users, can most effectively be achieved through the involvement o
f these ''affected'' communities, There is a need at the local, nation
al and international levels to ensure both the involvement of ''affect
ed'' communities and that recognition is given to them for the signifi
cant and essential role they play in infection control.
