Australian Bigpond email address users. Is your mail being rejected?

This would be why:

Australian telecommunications provider Telstra has very recently implemented a "p=reject" DMARC policy for their primary email domains (telstra.com, telstra.com.au, bigpond.com and bigpond.com.au). What this means for senders is that it is no longer safe to use these domains in your from address when sending from anything other than Telstra's email platform. No using Telstra email addresses to send mail from your ESP, CRM or newsletter platform -- these domains are now configured so that ISPs are encouraged to reject mail from these domains when not authenticated properly.

I couldn’t work out why the domain name expiry emails were’t reaching clients.

I am at a loss to understand why Telstra would do this.

Telstra Bigpond host mail for "msn.com.au" as well, and this is indeed reflected in the MX record for that domain. It points to a unique "extmail.msn.bigpond.com" but the server IP addresses behind that are the same as the normal "extmail.bigpond.com" servers.
