Kilmister Block is a 5.3km track that follows a creek through a valley within Belmont Regional Park. It is a mixture of single track and farm track, and crosses the aforementioned creek multiple times before joining up with Belmont ROad and Murphy's Track.
This particular cache takes you to a strange street address. Quite a desirable location for a house, but the property itself does seem a little....undeveloped. I have no idea why 1292 is located here, but I like to think that a time-travelling magic castle uses it as a semi-permanent caravan site.
