How to have multi-region replication for SQS messages?

I have an Active-Passive multi region architecture on AWS. We have cross-region replication for our RDS and DynamoDB; however, I'm not sure what to do with our messages in SQS when we failover. Based on the documentation there isn't a built-in feature for cross region replication.

Based on my research, the 2 solutions are;

  1. Use fan-out with SNS so messages will be sent to both regions.
  2. Have the secondary region applications get its messages from the primary region SQS queues.

The fan out pattern will not work for us because we need to come up with a way to determine if the message has already been processed by the primary region. We only have one active region at a time.

I was hoping for a more elegant solution than having the secondary region applications accessing the primary region messages. It's more expensive and introduce a little more complexity.

Is there a better way to accomplish having the secondary region continue to process messages where the primary region left off?
