Voice over for my PowerPoint (Austrailan accent)

I have created a PowerPoint presentation for Sexual Harassment, Bullying etc. to be sent to all new employees of our company. I would like someone to turn this into a video with a voice over. At the moment the PowerPoint is just all words. Ideally I would like the main points to be summaried on the PowerPoint and the existing words to be used like a script. I have already used software but it sounds very robotic. Looking for an articulate Australian accent.
