Sweet: Chandler Powell gushed about girlfriend Bindi Irwin as he left Australia for his native US

'It seems like just yesterday I arrived in Australia for your birthday,' Chandler wrote in part of his post, with Bindi's 18th birthday being in July. 

'I always carry even the smallest of moments, like these sunset walks through the zoo, with me no matter where I go.'

'Counting down the days until I'm back with you again creating more incredible, unforgettable memories.'

'Had the best time driving through the Glasshouse Mountains Christmas shopping.'

'Hiking, looking for wildlife, stopping at little towns in the mountains...,' he added. 

It comes after Bindi took to Instagram to gush about Chandler as she waved him goodbye at the airport.

The daughter of late Crocodile Hunter Steve Irwin wrote in part of her post: 'I miss you so much already. You really do mean the world to me.'

Upon seeing the post, Chandler responded in an equally affectionate manner.

He said: 'You are my world and mean everything to me. Thank you for the best adventures and memories I could ever have wished for. I miss you so much already but will see you soon.'

Before flying back to his native Florida, Chandler had been helping out around Australia Zoo and joining Bindi in her wildlife conservation role.

Chandler's return home comes in the wake of Woman's Day reporting that the loved-up pair were set to move in together.

The publication also reported that they were soon to become engaged, rumours which were dismissed as 'false' by a spokesperson for Australia Zoo. 

The pair have been dating for just over two years.
