That's the first problem, is when a SEO company has a sales team who promise the world, but the people actually doing the work you never meet them, then you have "client facing people" who go and give all the presentations.
Most bigger businesses are really switched on to this now some big tenders I have been involved with the procurement teams actually want the people who are working on the account to be involved with the pitch. .
But in regards to the original questions: SEO companies who are decent in the Australian market place for SME business and who I would personally recommend after 7 years in this business:
http://www.kwasistudios.com (South Australia Target Market) Ask for Woj, he is a really nice bloke knows his stuff, met him at a few conferences he knows his stuff.
http://www.123seo.com.au/ (Brisbane Target Market) Dejan SEO's small business offering, these guys are decent, I have met them at a few conferences and events they know their stuff.
http://anseocompany.com.au (Perth Target Market) Ask for Bob, he is a nice guy who deals with SME SEO, been around for a few years, knows his stuff.
And finally if you really want to ask the questions and meet some decent SEO's don't beat around the bush talking to sales people do direct to the SEO events -
http://seomeetups.com.au/ is a free event series in Sydney, Brisbane and Melbourne where you can talk to SEO's for free.
