Based off previous experiences with XPED and if I lived in Melbourne I would email both the ir and info email addresses asking to view the top 20 shareholders report on site.

If I had not received a response within a day I would followup with a phonecall.

I would provide "When requesting a copy, you must provide your name, address and the purpose of your request." Based on my purpose I may be denied. I myself would be viewing it for investment purposes. I would also request the costs involved in viewing the document so I know up front on the costs.

They can deny  if purpose is improper.
You cannot obtain a copy of a register for an improper purpose, such as:

• soliciting a donation from a member
• soliciting a member of a company as a stockbroker or sharebroker
• gathering information about the personal wealth of a member, or
• making an unsolicited offer to purchase financial products such as shares or units off-market
• if the company keeps the register on a computer, the company must provide the copy in the format set out in Part 2C.1 of the Corporations Regulations.

If I was advised that I could not see it then I might contact ASIC.

This is just my opinion on what I might do if I lived in Melbourne. What you do is entirely up to you.
