Koombana, in my opinion, went down NE of Bedout Island as described in detail in this blog. It is assumed that the wreck lies somewhere in relation to the so-called 'oil patch' dependent on accuracy of a plotted position (Captain Upjohn of the Bullarra). It is also assumed that the wreck is largely intact, enduring more than a decade (112 years) and as such has remained 'in one position'.
The following link describes in detail the powerful impact hurricanes can wreak on wrecks, causing destruction and movement. We also know that the broader Pilbara has been ravaged by a number of destructive hurricanes since 1912.

Furthermore, there has been significant seizmic activity NE of Bedout Island which, theoretically, could have caused further, significant wreck damage. In searching for the wreck of Koombana she may no longer be an intact hull; a single mag target; magnitude equating with +/- 3000 tons.
"Biggest earthquake recorded in Western Australia:The 4.9 magnitude earthquake recorded in Broome isn't the biggest earthquake Western Australia and Broome have felt. In 2019, a magnitude 6.6 earthquake struck approximately 200km west-southwest of Broome on July, 14th at a depth of 10km."
