@Yolande1932 : Yes, you'll still be using you current SIM.
As it is not in EU, you may only use your usual UK allowances there if you buy for £11.40 / month or have already as a Smart Benefit the Roam Abroad Pass or you have an EE Max Plan. Otherwise you will need to pay the charges or buy roaming add-ons as set out in https://ee.co.uk/help/help-new/roaming-costs/countries/australia .
If you are on contract, remember to text ROAMING to 150 before you leave UK to ensure roaming is enabled on your account.
