Police in Victoria launch a major investigation into alleged corruption connected to the Metro Tunnel project, according to multiple outlets. The investigation is led by Taskforce Hawk, which begins inquiries after the matter is exposed in media reporting. The articles say suspected wrongdoing has been known to some Victorian state government officials before the taskforce begins its work, but formal police action starts only after the public reporting.

The sources describe the alleged rort as involving a multimillion-dollar scheme tied to the Metro Tunnel project, though details of specific allegations, individuals, or contracts are not set out in the provided summaries. Across the coverage, the central point is the timing of police involvement: it follows media revelations rather than earlier internal or governmental knowledge. The articles frame the launch as a significant investigative step, with police seeking to determine whether any offences have occurred and to establish the extent of the alleged conduct.
