Speaking at a launch ceremony on site in Siffleet Street, Bellbird Park, both leaders praised the work of COC's natural disaster arm Global Care for its work in the area during last year's devastating Queensland floods.
Cr Tully had labelled Global Care volunteers in their trademark blue T-shirts "blue angels" when they arrived at his flooded home to help with clean-up.
"I still remember January 2011, and I am still quite emotional. I will never forget looking down the road and seeing a sea of blue marching around the corner almost with military precision.
"They were so cheerful and happy, and they did in 45 minutes what would have taken us two days.
"My wife Lisa and I will remain eternally grateful to Global Care's 'blue angels'. I could not speak more highly of them.
"They were angels for the people of Ipswich and Goodna, and they will never be forgotten here.
"I think it is great that the local church is able to provide funding for social welfare through its Bellbird Chase development – it's a win-win for everyone," he said.
Jo-Ann Miller MP, the State Member for Bundamba, said Global Care and COC had stepped up to the mark and provided enormous support for the local Ipswich-Goodna community.
"The profits from the Bellbird Chase development will go to the future work of Global Care, and I hope the land will be snapped up.
"It is very good land, and both the land and house-and-land packages are priced very affordably for working families in our community.
"It is also in a very good position, right across from the widely respected Kruger State School, and people can walk to the Kruger Park Shopping Village and a bus stop.
"I am more than happy to lend my support to this wonderful, caring organisation. Everyone is a winner. Let's hope it is snapped up," she said.
Bellbird Chase Project Manager Matt Flegler said he believed the Bellbird Chase development offered some of the best value real estate in Australia.
He said: "The potential for property value growth is enormous – this is well-situated, rolling land, surrounded by trees and greenery, and right in the centre of a future boom area with the launch nearby of Ripley Valley, the largest master-planned community project in Queensland.
"House and land packages for a four-bedroom home are around $310,000, which is very good buying."
