A memorial service for police constables gunned down in a deadly ambush in rural Queensland last week will be the scale of a state funeral, with up to 8,000 people expected to attend.
Rachel McCrow and Matthew Arnold will be farewelled at 10am on Wednesday at Brisbane Entertainment Centre, at Boondall in the city's north.
Free tickets were released on Monday, and the service will also be broadcast on free-to-air television.
