The good thing is that Lake Keepit is a get-away-from-it-all type of place, dedicated to flying and having fun. That's also a drawback when it comes to munga and woobla* where LKSC has an excellent reputation for all that, on a strictly bring your own basis.
During the comp, you should not have to worry too much about where food is coming from but if you plan to arrive early for practice, then you should plan to bring most food with you, either from somewhere like Sydney or more locally.
The nearest centres where you can buy provisions are Manilla, Tamworth or Gunnedah. There's not much of a choice in Manilla but it's a fraction closer than the other two. Tamworth and Gunnedah have a good range of supermarket type food and a few restaurants… but don't expect much in the way of a Michelin star. In fact, many local 'restaurants' are chain takeaways and would rate -2 starts as in "A restaurant worth a detour (to avoid)."
Ask a club member for a recommendation if you want to eat out. The Royal Hotel in Manilla and the Canberra café are interesting cultural experiences.
The clubouse at LKSC is the centre of apres-gliding activities. Outside the clubhouse, there's a BBQ area, tables and chairs where people get together as the sun goes down to discuss the events of the day, often well into the night.
Inside the clubhouse, there is a full kitchen, fridges, a dishwasher, stoves and microwave ovens. Most evenings you'll see a lot of pilots engaged in experimental cooking of one sort or another. It's normal for one person to do the cooking and experiment on serveral others. This experimental desert went down very well indeed.
Just because you are a glider pilot, there is no reason not to enjoy decent munga and woobla. As many-times world gliding champion George Moffat said, 'A club with a good bar cannot fail.' I think he forgot about the kitchen bit because he was speaking in the UK.
Some visitors choose the hunter gather route and look for wildlife in the lake or on the strip, and the wildlife and bush tucker at LKSC can be top notch. Fush caught fresh from the lake by New Zealanders…
That being said, the kangaroo is somewhat of an Australian national icon and it's not aways polite to eat that, at least not one you have caught yourself.
Munga and Woobla*
(These are Australian words to describe food and drink. Munga almost certainly came back from France with soldiers returning after the Great War and would be derived from the French word "manger" meaning "to stuff your face". So, for example, if you had shared someone's curry one night at the clubhouse, you might reply "Bonzer munga mate!" or not as the case might be.
The word woobla normally means cheap wine, often in flagons, but can be any type of alcohol. Typical usage would be "Have some woobla boss. Make you feel glad plenty quick." Australia has a lot of good fighting woobla, most of it reasonably price (if you buy it from Aldi) and there's normally bottles of all sorts of woobla for sale in the clubhouse.
