Hi Kate,
Yes, Nearmap imagery works well with SSA.
You can use either WMTS or WMS, either way you will need to setup an API key with Nearmap and then add the WMTS/WMS as an external basemap in Spatial Manager. Try WMTS first but if you have issues with alignment you might want to try WMS as this might be more reliable depending on which coordinate system you are using in SSA. (note WMTS is generally faster).
