The fire impacted on the dune system until it was contained.
The fire burnt around 1200 hectares of the marine plain.
A bushfire burning on Curtis Island since Sunday 28 May 2023 has been contained, protecting the island’s national listed key value parabolic and fore dune system.
The Queensland Parks and Wildlife Service (QPWS) believe the bushfire was deliberately lit, and fire investigators are continuing to gather evidence.
The bushfire branched out into two fronts, with front heading in a north westerly direction that is expected to self-extinguish against saltwater mudflats, salt pans and country that underwent a planned burn in March.
Another front burning in a south easterly direction has impacted on approximately 200mx200m of dry melaleuca swamp on the eastern side of the marine plain.
Rangers are currently mopping up the fire, and there is constructed bare earth containment lines to the west and South of fire ground.
The fire has not impacted on the she-oak forests in the dune system, but it has burnt through around 1200 hectares of the marine plain.
QPWS rangers have worked diligently to prevent the fire from threatening sensitive ecosystems, including fire sensitive coastal dune forests and threatened species habitat.
Rangers will continue to monitor the fire ground into the weekend to ensure the fire is contained and extinguished.
Anyone with information about the bushfire is urged to contact the Queensland Police Service or the Queensland Parks and Wildlife Service on 1300 130 372.
