For more on marking an answer as the "Best Answer", please visit our FAQ.Sorry, Lit_Rhapsody, but you are wrong. The UK is not a Schengen signatory and, to travel to Belgium (which is a Schengen signatory), a passport will be required.
As you leave the UK, you will be required to show your passport which will also serve as photo ID for security.
On arrival in Brussels, you will have to present your passport to the Immigration Officer. Whether your expired British passport will be acceptable and whether you would need a visa in your Australian one are a different matter. Maybe someone else will coment on this.
