Sydney Attractions Group is celebrating Mother’s Day by offering free entry for mothers at Sydney Aquarium, Sydney Tower and Sydney Wildlife World.

To take advantage of the deal, mums just need to be accompanied by another full-paying adult or their family over the weekend of 10-11 May.

The ‘mums go free’ deal also applies to Sydney Tower’s high-altitude adventure, Sydney Skywalk, which gives them the chance to venture out onto the Tower’s rooftop, 260m above the streets.
