I understand if you spend 14 days in SA and wish to go to WA you must apply to WA three days before for entry date. But getting into SA is the catch. Victorian's are basically refused entry now but other states eg Qld are ok for straight forward entry by permit to SA. And flights back from WA toQld are open as well.
Check each states Covid travel restrictions and entry and permit plus QR code arrangements prior to applying so you understand each states arrangements.
I have found contacting and speaking face to face over the phone is easiest and you can double check with any questions. Ringing in non peak times is advised to save waiting times.
I have also checked my Grand Final Guarantee which is a No1 priority and is guaranteed. Category Priorities Nos 2,3 and 4 may be subject to a ballot. If in doubt call our Membership Department who don't have a lot of info but have advised twice of info in this paragraph. Just also check that they have you marked which Category. You are then advised of your opportunity to purchase your ticket if you are eligible.
