Ummm, guys, Mansfield was CEO of Optus when it bought Aussat and started ops in the early 90s. Was only after Optus was standing strongly on two feet he left for Telstra to bring it "up to speed" in the competitive environment. Never understood how Stardust followed his footsteps. Ziggy never did a good job. Guess that's what happens when a photo lab technician runs phone companies. Telstra continues to trade as an incumbant, ripping off those who don't know better or who couldn't be bothered to shop around.
And not professing to be a huge Mansfield fan but he left Maccers before their downturn (mid-late 90s) and his replacements did an amazing job at stopping the blood loss ... his replacement Charlie Bell started work at the coal face as a 15 year old and ended up recently as their US Chief of operations.
