Summer is here and Chris is excited. That is until Ginger lets slip that the Summer Fairy isn't real. Meanwhile, Matt starts his journey to uni, Robbie works hard on a super ramp and Ethan makes a mysterious discovery in the greenhouse.

A boy, Heath, calls Ginger and Ethan and Robbie are spinning. When Ginger invites him over to spite them, she also gets confused. Is this a date? Penny thinks so. Also, Matt keeps tabs on Chris during his adventure to a neighbour's house.

Aunt Corey's psychic powers have gone from good to amazing. Ginger, Robbie and Ethan get suspicious-- where is she getting her information? Uncle Bob thinks Matt needs to get a job, but Matt has his own money-making ideas.

Matt and Chris share a birthday and always have a joint party. But with Matt turning 18, and Chris still being a grown-up, this could be the year things change. At least Robbie and Ethan will never stop playing their messy birthday pranks.

Ethan and Ginger stumble upon Matt's big secret and find out why he's been so mysterious all summer. While they try to convince him to come clean to Corey and Bob, Chris enjoys his invisibility ring and Robbie builds a giant battle-bot.

Ethan and Uncle Bob discover an old map that leads to 200 year-old pirate treasure somewhere in the garden. Ginger, meanwhile, worries that she's losing her Aussie-ness and gets help from Penny and Heath to re-discover it.

Ginger meets Tabitha, a cool Aussie girl, but is worried they can't hang out because she's older. Maybe she can persuade Matt to start dating Tabitha? Meanwhile, Robbie, Ethan and Chris blackmail Uncle Bob to upgrade the treehouse.

Someone has broken Uncle Bob's new TV, but none of the kids are talking. Aunt Corey and Uncle Bob sort through Ginger, Robbie, Ethan, Chris and Matt's stories to figure out which of their dear children committed the crime.

Ginger's secret is revealed. Now she has to work extra hard to get the boys to forgive her before she goes home to Australia. The boys, meanwhile, busy themselves by throwing their parents a fun new wedding.
