Hallo! So I work for a group in Sydney called 4U2Sing Karaoke, here's a list of all our shows.
Dunkirk Hotel, Pyrmont Tuesday 7-11 and Friday 7-12
Hotel Rockdale, Rockdale Thursday 7-11
Grand Hotel, Bondi Junction Saturday 9-12
Bellevue Hotel, Paddington Saturday 7:30-11:30
Rag n Famish, North Sydney Saturday 8-12
Hornsby Inn, Hornsby Thursday 7-11
Wallacia Hotel, Wallacia Friday 8-12
I think that's all of the weekly 4U2Sing shows, I only host at the Dunkirk and Rockdale, the others are with other hosts in our group. We have the biggest song selection in Sydney, incorporating legacy and community brands, all on board.
There are a couple of shows I go to sometimes called Karaoke Bare (singers are encouraged to sing in their underwear in the last round for a chance to win cash) those are at Palms on Thursday from 11pm and Tribe on Sunday from 8pm, both in Darlinghurst. I don't think they have a set finish time, they just do 3 rounds with breaks and prizes and it's Singa streamed Karaoke, both gay bars hosted by a drag queen.
There's a karaoke on Wednesday at Scruffy Murphy's in Sydney City. I haven't been there in a good while so I don't know what time it runs. They have a very limited on board song list. I know there are others in Sydney but I can't think of them right now cos I don't go to them.
