According to the Sydney Morning Herald, Roxy spent in the region of $5K for her 180cm tree complete with candy cane mansion and a stunning light installation in her backyard.
'Still blows my mind a week later. Thank you for this magnificent display of lights in my gardens,' she wrote on Instagram.
But Roxy is not the only one to splash out big time on Christmas.
Radio host Jackie O also splashed out on a Mermaid inspired tree.
'Loving our new mermaid Christmas tree this year. Thanks to Alana from Dancer and Dasher for the install. At night it is even more spectacular,' Jackie wrote on Instagram.
'Love the fact that you can choose a different tree every year and you don’t have to worry about taking it down. Win win!!!' she added.
