Under the AASB (IASB) conceptual framework income is now subdivided into:

gains, which are regarded as constituting a separate element in the framework; revenues, which may only arise in the course of the ordinary activities of the entity.

revenues, which only include sales, fees, interest, dividends, royalties and rent; gains, which are no different in nature to revenue.

increases in equity referred to as gains; reductions in liabilities which are classified as revenues.

revenues, which arise in the course of the ordinary activities of the entity; gains, which may or may not arise in the course of the ordinary activities of the entity.
