It's hard to call who's cooler: Roger Federer or the Teenage Mutant Ninja Turtles!

The lucky peeps at Suncorp SunWise Kids Day didn't have to choose when FedEx and the TMNT gang turned up, PLUS Serena Williams and Victoria Azarenka!

Don't freak non-Queenslanders - the Kids Tennis Day is coming to Melbourne, Sydney, Adelaide and Hobart soon!

While Feds can't be at every event, you could meet stars like SpongeBob SquarePants and Jai Waetford who will be performing at the Sydney event. But never fear Melbournites – Roger Federer is the official Melbourne Kids Tennis Day ambassador and will be joining Guy Sebastian, Samantha Jade and the Stafford Brothers at the Rod Laver Arena Spectacular!

Here's the deets:
  • Melbourne: January 11, 2014 at Melbourne Park
  • Sydney: January 6, 2014 at Sydney Olympic Park Tennis Centre
  • Hobart: January 4, 2014 at Domain Tennis Centre
  • Adelaide: January 5, 2014 at Memorial Drive
