Gold Coast for 2 & 4 year old girls

We are going on a family trip to the Gold Coast in a few weeks (Arrive Mon - Depart Sat). I have frequently been up there over the years but not with my kids.
We are planning on going to Bluey’s World on Friday and I wanted to take them to one or two of the theme parks, possibly Dreamworld? I am just not sure what would be more suited to their age group as it’s been a while since I’ve been to a theme park up there!
Otherwise open to suggestions for other activities to do or things to see, we will also be driving so will have our car to easily go where we need to - ideally don’t want to travel further than 45 minutes one way.
And also if there are any kid friendly pubs/restaurants around Surfers Paradise, would be greatly appreciated!
