The mission of the Lock the Gate Alliance is to protect Australia’s natural, environmental, cultural and agricultural resources from inappropriate mining and to educate and empower all Australians to demand sustainable solutions to food and energy production.

The Alliance is committed in all its activities to the following principles:

1. That robust scientific assessment, the precautionary principle and the principle of intergenerational equity should guide decision-making.
2. That communities should have the ultimate say, within the context of principle 1.
3. That it will support all and any communities who support the objectives of the Alliance.

Through its organisation and campaigning against inappropriate mining, the Alliance has five central aims:

1. To protect Australia’s water systems.
2. To protect Australia’s agricultural land for food and fibre production.
3. To protect Australia’s bushlands, wetlands and wildlife.
4. To protect the health of all Australians.
5. To protect Australia’s Aboriginal and cultural heritage.
