Dog Park Features & Amenities

For the Dogs

  • CRITICAL SAFETY WARNING: Unfenced on Busy Roads. The ovals are not fenced and are bordered by busy roads like Illawarra Road. This park is only for dogs with perfect recall.
  • Sports Have Priority: The off-leash permission is immediately cancelled if any field is being used for organised sport.
  • Bring a Bowl: Human water bubblers are available, so you’ll need to bring a portable bowl for your dog.
  • Bring Your Own Poo Bags: There are no bag dispensers, so you must bring your own to keep the sports fields clean.

For the Humans

  • Public Toilets: Public restrooms are available in the main amenities building.
  • Seating and Shade: There is some bench seating and a few mature trees providing shade around the perimeter of the ovals.
  • Playground Exclusion: Dogs must be kept clear of the children’s playground area.

Insider Tip: Before you let your dog go, do a quick scan for any teams warming up or training cones on the fields. Weekends during winter are the most likely time for sports, making weekday visits a safer bet for a guaranteed off-leash run.

The Final Verdict

HJ Mahoney Memorial Park is a fantastic local dog-friendly park, offering a huge amount of space that’s hard to find in the Inner West. It’s a social and vibrant spot perfect for exercising an energetic dog. However, its value is entirely dependent on sports schedules, and the unfenced nature next to busy roads demands a very well-trained dog. For a responsible owner with a dog that has flawless recall, it’s an excellent local choice.
