Interesting point, especially given all the bad IT practices at Optus that have hit the news the last year or so - and that’s just the bits we know about.

Smells like management have a lack of respect for IT and there’s a distinct lack of seniority. Telstra can afford to employ the best - and have to - to satisfy the requirements of their large government/defence customer base. Optus IT seem to be a bunch of Yes people who do the wrong thing frequently, probably under pressure from the hierarchy.
