The Simpsons visit it when Bart makes a prank call asking what way the water goes. Bart then leaves the phone off the hook, raking up a huge bill for them as he made a reverse call. The guy sues him and Bart has to travel to a court in Australia. He ends up letting Bart Junior (a bullfrog) free and this results in a lot of bullfrogs infesting Australia, which there weren't previously. This is a reference to cane toads, which are a poisonous species of toad introduced to Australia, which are now a pest found in New South Wales, Queensland and the Northern Territory, considered as a pest.
Bart ended up calling an Australian bar using Denis Leary's stolen cell phone to play a prank call. Specifically, he called an Australian Bar called Crocodile Drunkee's requesting for a "Drew P. Wiener" causing the barkeep to call out for the person and stating, “I have in my hand a ‘Drew P. Wiener’.” The patrons laugh at him and tell him that he'd "better put it down, mate!", to the barkeep's frustration.
