Queenslanders presented almost 25,000 animals to the RSPCA in 2015, leaving centres "consistently full to busting", spokesman Michael Beatty says.

Some people bringing in animals had to wait up to two weeks for full assistance due to the overwhelming demand.

Almost 25,000 animals were surrendered to RSPCA Queensland in 2015.

Re-homing and reuniting rates of pets in Queensland rose to 87%, however almost every centre experienced an increase in the number of animals received.

Wacol and Dakabin, home to the two rescue centres closest to Brisbane, took nearly half of all Queensland cases and collectively received about 600 more animals than in 2014.
