In short:

Spanish authorities say they have identified 69 victims of the crash between two high-speed trains in Spain, including two Australians.

The accident was Spain's second high-speed train collision this year and raised fresh questions about the country's rail safety, after a crash in the southern region of Andalusia in January killed 46 people.

What's next?

DFAT says it is providing consular assistance to the families of the two Australians.
