Hello,
input errors and overruns...are you actually experiencing performance problems ? The input errors and overruns usually mean that the router cannot handle incoming packets fast enough.
A simple shaping policy like the one below could remedy this. I don't know what the subscribed bandwidth is you have with Telstra, but let's assume it is 250MB.
policy-map Shape_Out
class class-default
shape average 250000000
and apply it to the interface:
interface GigabitEthernet0/1
service-policy Shape_Out out

Hi Paul,
Input errors could be generated by a bad cable or duplex mismatch, also I see 1 lost carrier error. Clear the counters and see if the counting stops otherwise contact to your ISP to open a case and certify the cabling. The overrun can be mitigated applying a policy map as provided by Georg.
