A share house lease may involve your share of the rent, bond, utility bills, internet and sometimes a pet or key deposit, depending on the agreement. Before signing, confirm how rent and bills will be divided, when payments are due, and whether everyone is jointly responsible for the full rent if one housemate does not pay. Bond rules and allowable fees differ between states and territories, so check your relevant residential tenancy authority and make sure the bond is lodged correctly. A written housemate agreement can also help prevent disputes about bills, cleaning and replacing departing tenants.
