Most employers will automate their super payments using their payroll software, such as Xero or QuickBooks. However, if you wish, you can use the Small Business Superannuation Clearing House (SBSCH) instead.
SBCH is separate entity from Wrkr. Nonetheless SBCH seems to have issues which probably benefits the online offerings such as Xero, MYOB and Quickbooks

The government-provided Small Business Superannuation Clearing house, used by around 130,000 small employers, is ill-equipped to handle payday super. It cannot process multiple payments in quick succession and has a history of delays.”
While there could be benefits, there could be also disadvantages if there are small business customers using these packages face challengers managing cashflow to make more super payments. Hence their lobbying for the delay.
