Sydney Morning Globe
From Tardis Wiki, the free Doctor Who reference
The Sydney Morning Globe offered $20,000 to anyone who could provide genuine pieces of Skylab debris. In 1979, Harvey considered taking his Skylab debris to the newspaper. (PROSE: Bennelong Point)
Behind the scenes
In real life, it was the San Francisco Chronicle that offered the exorbitant award, and the real life person on whom Harvey was based did indeed get a flight to San Francisco to successfully claim the prize. Also, in real life, the name of the paper is the Sydney Morning Herald.
