Australian Commercial Owners Mobile Leads

I need a fresh, accurate list of Australian commercial property owners, with a strong emphasis on direct mobile numbers. Online research is the only method I want used, tapping primarily into professional networks such as LinkedIn, industry associations, and similar sources that reliably reveal ownership details.

The data has to be recent and verifiable. Where possible, please cross-check each mobile number against at least two publicly available references (for example, a company registration and the owner’s LinkedIn profile) so I can depend on its accuracy.

Deliverables
• Spreadsheet (Excel or Google Sheets) containing:
 – Owner’s full name
 – Mobile number (mandatory)
 – Company or entity name
 – Property address or identifying details
 – Source link(s) for verification

Acceptance criteria
• Minimum 90 % of the mobiles must connect to the stated owner when dialled.
• All entries must pertain to commercial property, not residential or industrial.
• No recycled databases or purchased lists—online research from professional networks only.

If you have questions about the formatting or verification process, let me know before you start so we’re aligned.
