Not sure how long this has been effect, but Dreamworld have made some adjustments to their annuals passes.

They now have two offerings being either just a Dreamworld Annual Pass which is now $149, or an 'All Worlds Annual Pass', which includes all the additional perks for just $20 more.

For only $20 more the All Worlds pass is very good value

This was an early December change

Locals Annual Pass/Interstate Annual Pass > All Worlds Annual

Same thing, just no post code restriction/same price for everybody. $10 price increase from previous locals pricing to $169 online (full price).

Saver Annual Pass > Dreamworld Annual Pass

Value Annual Pass no longer available

There’s also the seasonal WWW pass @ $99 and Groupon has a $99 Dreamworld Annual with “Interstate Residents Only“ in their terms

Approximately a week ago they introduced a “limited time offer” for Locals only at $124 Adults/$114 Kids for the All Worlds Pass.
