Assistance Required for Incorrect Shipping Calculations

Hi,

We’ve been experiencing recurring issues with the Australia Post WooCommerce plugin not calculating shipping costs correctly.

Shipping Details:
From: LEETON NSW 2705
To: PERTH TAS 7300 (Parcel Post)When Calculated Manually via AU Post Calculator (One by One):

• Item 1: 50 x 50 x 60 cm | 13 kg → $197.75
• Item 2: 42 x 31 x 18 cm | 21 kg → $107.65
• Item 3: 28 x 15 x 5 cm | 0.3 kg → $10.95

Total: $197.75 + $107.65 + $10.95 = $315When Added to Our Website Cart (Parcel Post):

Instead of calculating correctly, the total shows only $178.20.

Issue:

The website’s shipping calculation is significantly lower than the actual cost calculated via the AU Post Calculator.Question:

• How can we configure the plugin to correctly split packages based on their weight and dimensions to match the Australia Post Calculator’s results?
• Is there a recommended setting to ensure the calculation aligns with the AU Post Calculator for accurate pricing?

Thanks
