Need help to identify two species, possibly rodents. The first lot is a pair tail 65mm, body - 75mm, rear foot - 20mm, 9gm. The second lot is a group of six, tail - 40mm, body - 45mm, foot - 15mm, 3gm.

All are independent, furred, eyes open, self-feeding on a variety of foods. We are in Townsville but are not discounting possible rail travel.
