Ann: 2018 first half financial year results - investor briefing, page-326

As tessastanle pointed out, Intelligent Investor also have their retail fund which will follow their recommendation. It is effectively a pooled retail fund. The stock has been pushed a long time by them and there would many holders who would have panic dumped today and further stop losses would have triggered other traders. It really looked like a capitulation today.

Every substantial change notice has been showing increases. If there is 'inside info' these funds would be closest.

Only outside possibility for today's drop is a potential CR looming, if debt covenants are at risk.
