Allan Brent is thrilled to be taking part in a huge challenge - climbing the Sky Tower 16 times - alongside his mother, Anna, who has battled hard since being diagnosed with breast cancer two years ago.
The challenge - dubbed Step Up For a Cure - is raising funds for the Breast Cancer Research Trust.
Allan and Anna will be joined by her husband David, a group of Allan's friends, and celebrities Monty Betham, Shane Cortese, Jaquie Brown and Geeling Ng.
In total, 15 people will climb. By yesterday afternoon, they had collectively raised $11,846 for the cause.
Allan Brent, 24, said he was inspired to do it after making a promise to his mother that they would climb Mt Aspiring together one day - something they have both done separately.
