Hmmm depends on what you're after, if it's 90s kids shows I can recommend a lot but they're bad in a 90s way.
For more modern, adult shows - I don't watch much TV any more but let's see.
Mr Inbetween - A dark comedy about an ex-soldier turned crime family hitman. Caring for his family inbetween killing dodgy people.
Fisk - Comedy. Haven't seen but hear good things, about a lawyer who loses everything in her life and moves from Sydney to Melbourne to work at a small firm.
Rake - It's like House but with a lawyer.
Colin from Accounts - RomCom Drama, not my type but it's got good reviews.
Utopia - Australian government bureaucracy comedy. There's also their previous show 'The Hollowmen' which is more about the governments PR firm getting them elected.
Underbelly - A retelling of Melbourne's gangland wars from 1998–2010. Probably one of the greatest crime shows I've ever seen. Can also watch Eric Banner's movie 'Chopper' to get a different feel for one of the most notorious people during the time.
Bluey - It's Bluey
Kath & Kim - Older comedy about bogans.
Wilfred- Older comedy about a man dressed as a dog, was also remade into a more boring American version.
