Would it be normal practice to rinse/wash and sanitise bottles before filling? This is probably the main area where I don't know if I am assessing the risk correctly. The bottle supplier we have in mind has ISO, but then there is the risk of contamination posed by transport, storage and even staff handling.
It's going to depend on the format in which the bottles are supplied to you, but in many cases best-practice would be a combined wash and inversion, as that also address the risk of foreign body presence arriving in the empty bottles.
Given your product profile, getting your preservative type and levels right is potentially going to be relevant for quality / shelf life, even if not for pathogen control. I don't know how the regulator in Aus views moulds, but even at <0.85 aw there is some potential for growth, and here in the UK I believe there have been a few instances where regulatory bodies took the view that mould growth presents a food safety risk via the potential for mycotoxin formation. Similarly there are some yeasts that could theoretically cope in this type of product, and fermenting bottles exploding is something you want to avoid
Your product is perhaps at the peripheries of typical soft drink profiles due to the relatively low water activity, but this might be a useful read: https://www.research...lication_detail
