“Why did she resign? Pressure from citizens?”
Corruption.
But, more likely somebody who had the dirt on her and was tired of her tyranny got the investigation going.
Very possible. And when you have a tyrant that has not established complete control over the state apparatus, this may the best way to get rid of the miscreant.
That's what I was thinking too. Someone knew she was not exactly pure and dropped a dime on her.
The investigation initially centered on former NSW legislator Daryl Maguire, alleging that, while Berejiklian had been in a “secret” personal relationship with him, she may have “engaged in conduct that constituted ... a breach of public trust” by helping to funnel government grant dollars into organizations in Maguire’s district.
Maguire, who previously served alongside Berejiklian in the state’s Liberal Party, resigned in 2018 over a separate series of corruption allegations linked to property deals with an overseas developer.

The ICAC is also investigating whether Ms Berejiklian had a conflict of interest in connection with grant funding to the Australian Clay Target Association in Wagga Wagga (pictured)
