Upper Middle Bogan is an Australian sitcom about a middle class family discovering the lower class side of their family, so a bit like My Family meets Kath and Kim.
It was written by Wayne Hope and Robyn Butler. They've been around for a while, doing sitcoms like Librarians, and Very Small business. It was directed by Tony Martin, who's a comedy God in Australia, mostly known for his radio comedy shows, but he also co-wrote and directed movies like Cracker Jack.
The first season of Upper Middle Bogan came out a few years ago was mildly successful, but the second season came out at the start of 2015 was excellent.
Well worth a view, particularly the second season.
