Buy Physical Silver or if you cannot hold it, buy Silver Mining Company shares. Developers offer the best risk return profile. I am an Aussie and have posted about the Aussie ones before. There are only a handful of them on the ASX (Australian Stock Exchange) and they should all do well, though the entry prices right now mean in terms of risk reward I recommend this order at present - BML, SVL, RDM, MKR, IVR, TMZ, ADT, ARD, KCN
Here is a reddit post of mine with more details -
Here is a graph that shows the price you pay per Ag Eq ounce when you buy the shares today. The lower the better is the first guide, but then you look at the details of the Company itself and see what suits your risk/reward profile. Go to HotCopper.com.au to get announcements and discussion on each Company.
The light ones have resources in Australia, the others have resources overseas or are listed in the US or Canada for comparison purposes.
