What is this music video called?!?

Ok so I'm trying to remember the name of this music video, I saw it on youtube a few years back, the band sounded like the Jonas brothers, they were a boy band, I think they were Australian? In the music video they were at a party with these lantern things and then they rode around in this old Silver jeep cherroke, the boxy kind with california license plates and then the were on the beach? can anyone help me identifiy the band/music video!!!???
