Calendar Subscriptions

Does anyone know where I can find a subscribable calendar for school holidays (NSW for preference, Australia wide if thats not available).

Used to have one, cant remember why I deleted it, but now I want it back.

Anybody got a decent public calendar source?

TIA

Not quite what you want, but there is this:

I’ve got one for VIC:

Thanks, maybe there will be something somewhere

[edit]. Actually there are links from that page, which give calendar stuff. All good.
