"Steamroller Park", (I didn't know it was called that until I read it on Hurstville Council's website), was the location for my 8th birthday party and I used to visit all the time when Mum was studying at UNSW Oatley. Today, I returned with Mandalf to hide a cache on the steamroller I so enjoyed playing and climbing all over as a kid!
Try to visit on a quiet day - you won't be able to find the cache if there's anyone else there. There's plenty of free parking around, and read below for more info on the park's facilities. Best of luck!
P/S: Any feedback on the difficulty rating would be appreciated!
Some press on Steamroller Park from the Daily Telegraph (http://www.dailytelegraph.com.au/top-10-kids-playgrounds/story-fn5ftg6s-1225977074929):
"WITH it's mass produced blue, red and yellow plastic slides and climbing equipment, the Oatley Park playround is not unlike hundreds of others dotted around Sydney.
But what makes this site in Sydney's south special are the beautiful surrounds.
It is located on a huge open grassy space and surrounded by 45 hectares of peaceful native bushland leading down to Oatley Bay and the banks of the Georges River.
The playground is a decent size and in addition to the usual equipment and swings there is also an old steam roller nearby which kids of all ages love to climb over and pretend to drive.
But when they tire of the play equipment, the family can take a bush walk to other parts of this huge park or even head down to the sea baths for a swim.
There are wood-fired BBQs, lots of trees for shade and as one of Sydney' finest areas of natural bushland, Oatley Park is also known for it's prolific bird and animal life.
So bring a picnic blanket, some lunch and let the kids play all day as the cockatoos and lorikeets fly overhead. If you're lucky, you might even catch a glimpse of wallabies playing in the bush."
