From all the rumours and stuff i've heard, Perth has got to be the most likely destination. It flys between both Hong Kong and Singapore multiple times a day, which would comply with our 2 sightings in HK and sin.
However, I have been asking a few of my mates if the have seen couples running around Perth with bags and cameramen following them, seen clue boxes or seen Phil, and its all 'no' at this stage. However i'm travelling into the city asap, and if I see any teams i will try and follow them.
