Staff from Allianz and Brisbane-based Comsure Insurance Brokers will take to the trails of D’Aguilar National Park on June 20 to raise money for Oxfam.

They will start at Mt Glorious and finish at Mt Coot-tha, covering 100km overnight and into the next day.

Comsure Manager Marcus Hamill and Account Manager Eloise Borrett, along with Allianz Business Development Manager Randall Latham and Sales and Service Manager Nicole Stallard, have already raised about $16,000 for the Oxfam Trailwalker challenge.

Mr Hamill told insuranceNEWS.com.au it took three of the group 33 hours to complete the walk in 2012.

He says other brokers and insurers are supporting the team, called Apollo IV, which is one of the top fundraisers from the financial services sector. About 400 teams will participate in the challenge.
