Rowany is an oft used shorthand term for The Rowany Festival (sometimes called just "Festival") Australia's largest SCA event which is, currently, held at the Crossroads medieval village. Anything that people do in the SCA (well most things) will be on display in some form or other at Rowany.
Happens every easter - Don't miss it for the world.
If religious reasons are inclined to slow down your attendance at an event over easter, don't forget that a group of christians generally get together in a discrete place to hold a scheduled easter sunday mass. And if pasach falls at the same time of year, I'm sure there will be people cooking in accordance with customs - it's actually easier to avoid leavening agents in period cooking.

Hrmm.. so you're coming along and don't know what to take? Perhaps you need a camping list?
