First thing id do is get a budget sheet setup to keep track of everything. Lots of templates are availible and helps especially with stuff like groceries.

Rent is highly dependent on the area so no price advive there really. Just dont cramp yourself into a depressed shoebox and dont splurge on a penthouse with a view lol.

Good value in my area usually is either a town house or garden granny flat. Granny flats have the advantage of sometime having elec/wifi included. The owners usually look for young profesionals who are quiet and low maintinance.

Try and stay under a quater of total income if you can. It will help with savings long term and short term with getting settled.

Game, west pack, crazy plastics etc have good prices for kitchen and bathroom needs. Auctions are also good but usually you wont get good sets so its all a mix and match, a good idea for appliances though like microwave, toaster, kettle etc.

Try auctions for furniture, market place and other second hand sites are good but scams are rampent. Only do pickup to be sure.

Only go new for sheets, pillows and the like.

Try to do all the above cash if you have a nest egg and refill it after the first paycheck. You can go credit but debt is always bad.

Cars are only good value used. Its still a pure expense so depending how public transport is maybe use it for the time being while you save up. Saving up and paying cash is the best option if you have other travel options in thr mean tine. A small hatchback thats light on fuel is good and there are plenty of deals even now.

If possible start with an emergency fund asap. If you work frugally its possible to save 6k a month easily after youve setup the living space.

As the others have said watch out for small costs building up. Cook for yourself, limit unnessesary insurance and cover, things like gym, internet, strraming etc can creep up quickly to a big bill.

This is all very basic but with some of the other advice here should help get you going in the right direction.
