Optus chief executive Kelly Bayer Rosmarin has been the focus of public anger over the nationwide outage that took ten million customers off line yesterday. Ms Bayer Rosmarin is still apologising for the crisis but still doesn't have a clear idea of what actually triggered the outage. The embatted CEO has offered 200 gigabytes of extra data and free weekend data to appease angry customers. Kelly Bayer Rosmarin spoke with ABC's Peter Ryan.

The full financial and reputational impact is yet to hit Optus .. although the embattled telco is digging deeper in the crisis saying it's not planning to compensate customers.

This morning Optus released it half year financial results in Singapore and even though they don't include the impact of yesterday's outage, the company is already under pressure from rising costs from inflation.

Also today, the National Australia Bank posted a full year profit of $7.4 billion. Chief executive Ross McEwan speaks with me about interest rates, inflation and recession fears.

But on the Optus outage, he says while the NAB is resilent, CEOs "can never rest easy".

Optus is apologising but still can't fully explain what went wrong.

As was widely expected, the Reserve Bank has raised interest rates by a quarter of a percentage point, to 4.35 percent, despite evidence that households are already stretched.

It's the 13th rate rise since May last year, as the RBA continues its battle to contain inflation.

Michele Bullock's honeymoon over as Reserve Bank governor hikes rates for 13th time since May 2022. December hike chances at 28pc - get ready for the Philip Lowe treatment and headlines like "the grinch who stole Christmas"

After a relatively smooth induction as Reserve Bank governor, it seems the honeymoon's over for Michele Bullock. The RBA board's decision to hike interest rates for the 13th time since May last year means more pre-Christmas pain for borrowers and the real risk of a followup in the coming months, potentially in December.

The Reserve Bank is widely expected to raise its official cash rate by 0.25 percentage points to 4.35 per cent at today's board meeting. Economists believe Michele Bullock will be forced to act on inflation which remains well above the RBA's target band of 2 to 3 percent.

Will they or won't they? The Reserve Bank is poised for a lineball decision on whether to deliver the 13th interest rate rise since May last year. Economist Brian Redican says a hike will hurt households already on the brink while at the same time it's a test for the RBA's credibility on inflation.

It's shaping up as another line ball decision when the Reserve Bank board meets tomorrow - on Melbourne Cup Day - to consider what might be the 13th interest rate rise since May last year.

It's also a test for the new Reserve Bank governor Michele Bullock who's pledged to do whatever it takes to pull down inflation especially if it looks like running away.
