Now, if making fifty consecutive one cent transactions per day for (say) a Telstra bill is coming it a bit high (because most people would pay their Telstra bill completely once a month) then perhaps fifty random transactions, one every half hour on average, to various billers of small but higher amounts would appear more kosher. This could be scripted.
Credit card transaction fees might make it uneconomical. I tend to value QFF points at a cent each, so if the fee for a transaction passes five cents, I'm going backwards. At (say) 2%, that's a ceiling of $2.50 per transaction. Telstra charges 1%, making $5 the upper limit.
Now it may be that BW continues to allow fifty one cent payments to Telstra per day. If so, all well and good. But a safer approach would be to make larger payments to more accounts, and to do it over a longer period (say, ten to fifteen minutes between transactions).
