NBN 12/1 for $34 per month for the first 6 months, then $44.90.
25/5: $44, then $54.90.
50/20: $54, then $64.90.
100/20: $69, then $79.90.
100/40: $79, then $89.90.
If you're a pensioner or have other listed concession cards, you can get a few extra dollars off the base price from month 7 onwards (i.e. the price after the 6 month honeymoon, promotional price is the same as above). $39.90 for 12/1, $52.90 for 25/5.
Critical Information Summaries:
These guys are cheap, but it is unlikely they will go bust anytime soon. They sell other services as well, like Flip TV and some relatively uncompetitive (but hopefully higher margin) mobile plans.
They used to charge 2 months in advance, but that's not a thing anymore.
No surcharges for credit cards, so you can earn points.
I cannot see any references on their website about referrals. They might have removed it. I don't think they actually worked from the time I was with them. OzBargain would show multiple clicks, but no credits ever appeared on subsequent bills.
That 12/1 price seems to have coincided with the final price reduction of NBN 12/1 wholesale prices. It started at $27.40 before October 2020, was lowered to $26.60 in October, $24.70 in December and $22.50 in May 2021.
These changes are in addition to NBNCo’s proposed reduction in the effective charge of the 12/1 Mbps modified entry level bundle discount (mELB). The wholesale price of the 12/1 Mbps mELB will be reduced from $27.40 to $26.60 in October 2020, followed by further proposed reductions under WBA4 in December to $24.70, and a final reduction in May 2021 to $22.50.
Judging from the Whirlpool thread, most people on Flip Connect are on lower speed tiers (i.e. 12/1 and 25/5) looking to save money and have a bit of tolerance for lesser customer service. The people who can afford to pay more generally don't end up staying and quickly move onto more premium ISPs like Aussie Broadband or Superloop.
Depending on where you are located, these guys might block all ICMP traffic (including pings from CMD, like "ping google.com"). It can be a pain to get support staff to understand what you mean and unblock it. Worth noting if you're an IT professional or prosumer.
They use PPPoE for authentication and possibly CGNAT for IP addresses. Check the Whirlpool thread for more details.
Choose your speed tier wisely. A $99 fee applies for up and downgrades. For some reason, their Ts&Cs also say you will also be locked in for 2 years, even though the base plans are all no contract/month to month. Might be leftover clauses from when they used to sell lock-in contracts? > 11. Plan/speed Downgrades
If you request to downgrade your plan or speed during your commitment period, a $99.00 downgrade fee applies. The plan will take effect from the following calendar month with a new 24 months commitment period.
12. Plan/speed Upgrades
If you request to upgrade your plan or speed, a fee of $99.00 will apply. All upgrades will take affect from the following calendar month with a new 24 months commitment.
Comparisons with other ISPs:
$34 promotional pricing for NBN 12/1 is unmatched. Closest is SpinTel for $39 via a hidden page from comparison sites. For people with low standards, don't agree with the "lul, classifying 12/1 as broadband in 2021" comments and just want to save money.
Tangerine have a similar offering for 25/5. Promotional pricing is 90 cents more for Tangerine and the price after 6 months is $5 more as well.
Exetel's 50/20 offering has a promotional price of $50, $79 after 6 months.
It's hard to compare 100Mbps plans because ISPs are increasingly excluding the upload from their websites and CISes. A cynical view could be that providers who don't advertise upload are probably on 100/20 and the ones on 100/40 will painstakingly make it obvious to differentiate themselves from 100/20 plans.
Closest competitors I could find are SpinTel at $74 promo, $84.95 base (from the same hidden page linked above) and Tangerine at $74.90 promo, $89.90 base. Neither advertise upload.
Also worth noting Tangerine offer $25 credit for referrals. That's a little over $4 a month if you're only comparing 6 month promotional prices.
