Promotion after PR granted?

[Kingdom]

G'day, I got golden mail while I was overseas during my holiday.

See my timeline below, please. 

Does anyone know about promotion after visa granted?

I want to get promoted but I don't want to risk, of course.

Same occupation, job title or position but 1 level up from level 4 to 5 or 6 (max from this occupation), slightly doing more work according to paperwork, which is the jobs I already have been doing.

I don't have Migration Agent so please help me guys.

Thanks heaps in advance.

Pretty sure you’ll be fine if you stay with the same employer. Good luck!
