By designating the Petrie-Redcliffe route as a main road, Brisbane motorists would gain a high quality motoring road from the city to a seaside resort, while reducing Redcliffe's isolation. On 21 June 1922, the RACQ presented the case for the road to Harry Coyne, the Queensland Minister for Lands. Coyne agreed the road would likely be gazetted as a main road on the undertaking that non-government capital would be raised to begin its initial construction, while also suggesting the name of "Anzac Memorial Avenue". The Anzac Avenue Memorial Committee was established with Rothwell as chairman. A fundraising figure of was set. This amount would provide for the wages of ex-servicemen employed on the road, while the Main Roads Board would bear the cost of construction materials. Publicity for the fundraising appeal for the Anzac Memorial Avenue appeared in the Brisbane press on 1 July with the rationale for supporting the proposal:"Every motorist is interested in this scheme. It is surely worth at least 5 pounds to a motorist to have one good road. Every business man is interested. It is surely worth a good deal to relieve the labour market of its unemployed. Every citizen is interested. It is surely worth something to you to have a Memorial Avenue that will at once connect one of Brisbane's beauty spots and commemorate for all time the valour of our soldiers."As part of the public fundraising effort, a progress board was erected outside the premises of the Commonwealth Bank in Queen Street, Brisbane. A figure of a car moved forward in increments of 1000, towards the end goal of . 8 August was proclaimed as "Anzac Avenue Badge Day" with car badges sold to raise funds. Other events included social functions at Redcliffe. By December 1922, had been pledged by public subscription. The target of received a significant boost through government funding. In July 1922, the Australian Government, announced a National Main Roads Policy, allocating money to the state's road building schemes on a 4/8 federal, 3/8 state, and 1/8 local government funding arrangement. The objective of the policy was to "develop and open up the country, and promote land settlement, and aid temporarily unemployed soldiers". Through this funding, the Redcliffe road was allocated , a larger proportion of funding than any other of the first roads built under this funding agreement in Queensland. The combined public fundraising () and government contributions () meant that within six months of the appeal's inception, the goal of was close to being realised. Of the subscribed, a final amount of had been received by 1926, with the Main Roads Board making up the difference.
