you should be fine.
its only if its within the last 12 months, and i only came back just last june so i had to provide one.
This is what they emailed me before i attended AD.
Most importantly, if you have resided and worked overseas in the last 12 months (not on a working holiday) you will be required to complete an overseas police clearance in that country (including NZ). If this applies to you please contact us for more information. We recommend you take the steps necessary to obtain the overseas police clearance (if applicable, to your circumstances) as soon as possible as waiting times can be lengthy.
i took care of it before i even went to AD because i thought it might've taken long for it to come back. It didn't but then recruitment forgot about it which is why i waited a little bit longer than others.
frustrating at the time (i think everyone knows how that feels... just waiting and not knowing anything lol) but it was worth it in the end and now i don't even remember all that waiting haha
