Who is adsl2exchanges.com.au?

When I'm checking for exchange details for myself and friends here in Australia to see which companies have DSLAMs (Digital Subscriber Line Access Modules - the exchange side of ADSL) and on which DSLAMs ports are available, I use a website called adsl2exchanges. It's got some good tools by hooking into Telstra Wholesale etc. What isn't exactly clear, however, is who's behind the site.
