Shrek4 ha been caching since 2007 and despite a mosdest cache find count (443 at the time of placement) is a huge participant in the South Australian caching commuity (23 events attended). Its no surprise that they (along with numerous others) are involved in organising South Australias first MEGA event.
I've come across them numerous times, either at cache events or when have happened upon a SA MEGA meeting.
Keep up the good work Tobias.
