Nickelodeon has partnered with Nice Events to produce its third year of the family friendly music festival in Australia, Slimefest, which will be expanded to Melbourne this year.

Last year, Slimefest attracted more than 9,000 kids and families to its two Sydney shows. This year, Nickelodeon Slimefest will include four shows–two in Sydney on Sept. 26 and two in Melbourne on Sept. 28. Headline talent and celebrity guests will soon be announced.

Pre-sale tickets will be available beginning July 7 and a 90-minute version of the festival will air exclusively on Nickelodeon on Sept. 29.
