Police are encouraging people taking part in Anzac Day commemorations throughout Brisbane to remain vigilant as they crack down on security in one of their biggest operations of the year.
Acting Chief Superintendent Mark Reid said police had learnt from overseas terrorist attacks to be better prepared for big events in Queensland.
"The threat they cause can be outweighed by the planning opportunities they provide us," he said.
The Dawn Service in Brisbane's CBD will be held in Anzac Square from 4.28am. A main parade will start in George Street from 10am, with the route outlined in closed-off streets below.
A mostly sunny day for Brisbane is likely, with the Bureau of Meteorology forecasting a 10 per cent chance of rain.
The only weather that might affect dawn services was potential patchy fog in the early morning, but it was expected to stay mainly in the western suburbs.
Several months of planning has been dedicated to Anzac Day, with police on the lookout for anti-social behaviour, protests and potential terrorist activity.
Chief Superintendent Reid said the national terror threat remained at "probable" but he emphasised there were no known threats to Anzac Day events.
Tight vehicle restrictions will be enforced around the Brisbane CBD, with parking and access to closed roads limited to those displaying Vehicle Access Passes from 3am to 3pm.
Chief Superintendent Reid said the number of resources dedicated to the commemorations would remain the same, but how they would be used had changed, based on overseas incidents and reviews of previous operations.
