"The Queensland government has been a strong supporter of the Queensland Maritime Museum over many years and provided a financial contribution of $600,000 over three years (2018- 2020), with further funding of over $218,000 provided towards special projects."

It sounds like a decent bit of money had been given to them, though $200,000/year doesn't go all that far these days. The other $215,000 is presumably going towards restorations which I'm sure are ridiculously expensive. It's not like you can duck down to Bunnings for a few bits of timber to slap on your early 1900s floatyboi.

It seems like the place charges an entry fee so presumably they're offsetting at least some of their costs --> https://maritimemuseum.com.au/tickets/

Personally I'd be happy if more of my tax dollars went towards stuff like this.
