1300 303 723 - 1300303723: Local rate number, provided by Several Telcos

So we rang that number back and it felt dodgy as heck! When we chatted with Optus, they first said it’s a scam, but later they double-checked and came back saying it's one of their sales agents. What a mix-up, eh?

I checked with Optus, and let me tell ya, this number is definitely shady as all hell. Avoid it like the plague! Always go for the official number from their website!

Here we go again, folks! A shady email about my Optus order with a referral, complete with a dodgy 'PLS'. Just screams scam, eh?

I received a message that seemed legit, so I gave them a ring. The texts were all sent with the correct OPTUS name too.

I got a call from 1300 303 723 and could hear a bunch of Indian scammers chattering away in the background. My missus was about to spill all our details after I ordered a new iPhone, but thank goodness I stopped her. Total scam!

I believe this number is associated with scammers. Anyone claiming that this number is legitimate is likely being misled. Beware of this call.

I received a call from Optus confirming the details of my NBN order; the call appeared legitimate.

I notice that your comment appears anonymous. If you're with Optus, why the concern? You shouldn’t have anything to worry about.

They called from a landline 02 9174 3000 pretending to be from Optus then sent a sms message leaving this number. The name of the sms was OPTUS message. Luckily I had previous sms msgs from Optus and could compare (they were very similar only the scammer used capital letters in the OPTUS message name. Quite scary as I just ordered a new phone a few hours earlier, how did they know?

Initially, I found this call to be suspicious, but it turned out to be legitimate. After everything was confirmed, I received emails from Optus, verifying the details.

Legit: I received a text that initially worried me, but it included a reference number for my new phone order. After providing my details, I verified the order through a text and email from Optus, confirming its legitimacy. I can also track my order using the app now. Despite my initial concerns that it might be a scam, everything turned out to be fine.

The call appeared to be from Optus, and they had my order reference number, which suggests they may have access to Optus data. I chose to call back using the official Optus number to verify.

If you receive a message from this number, do not respond. It's a scam! Genuine Optus messages will come from the name "Optus" and only those characters. The following message sent from this number is fraudulent: "We need to talk to you about your Optus order. Please call us on 1300 303 723 with ref: YES01234567." I am not an Optus customer and have no orders with them.

I contacted the number 133937 for validation, and they confirmed that this phone number belongs to Optus.

I received a text message instructing me to call this number regarding an order. To verify, I contacted Optus using their official 1800 number, and they couldn't find the number in their database. When they tried to call it on my behalf, the call wasn't completed. They advised me to ignore the original message as it could be a scam.

The call connects me directly to an internationally outsourced Optus call center, which is apparently handling new internet and mobile orders. The overall feel of the call seems suspicious yet oddly genuine.

I received a call from the Optus call center. I'm uncertain if it was actually Optus or a third-party representative. I had to call regarding finalizing an NBN installation order. Although the number was provided in a somewhat suspicious email and there was a lot of background noise, it appears legitimate since I received both a confirmation email and text from Optus afterward.
