| Port Stephens entrance | Departure | Runout tide and swell can create dangerous water | Time and assess departure using current official and local information |
| Cabbage Tree and Boondelbah Islands | North-east of Port Stephens | Reefs, protected zones and breaking water complicate the route | Current chart, marine-park overlay and suitable offing |
| Broughton Island group | Early passage | Multiple islands, reefs, bomboras, dive activity and no-anchoring zones | Never use the illustrative corridor without detailed chart work |
| Broughton anchorage assumption | Optional stop | Shelter varies with wind and swell and departure may be delayed | Treat as a separate passage and anchoring plan |
| Forecast-zone boundary | Seal Rocks | Conditions can differ between Hunter and Macquarie zones | Review both forecasts before and during the passage |
| Bomboras | Seal Rocks, Sugarloaf and other coastal sectors | NSW warns bomboras can break at any time around reefs and shoals | Maintain charted clearance and visual lookout |
| Adverse south-setting current | Entire route | Can add hours and destroy the bar ETA | Compare log speed and SOG and recalculate regularly |
| No routine harbour | Broughton to Forster | Mechanical or weather deterioration can leave no easy refuge | Full weather window, reliable systems and preplanned alternate passage |
| Lee shore | Onshore wind along the coast | Failure can reduce recovery time | Maintain conditions-based sea room |
| Fishing vessels and gear | Entire route | Lines, pots and small vessels can be difficult to see | Daylight lookout and conservative clearance |
| Cape Hawke bar changes | Destination | Charted depths and safe path may not reflect current conditions | Expert local knowledge and current visual assessment |
| Ebb or runout current | Bar and harbour | Can create compression waves and strong set toward the bridge | Prefer suitable current under local advice and define abort point |
| Forster-Tuncurry Bridge | Immediately inside | 6.0 m clearance at high water blocks most yacht masts and creates collision consequence | Remain in confirmed seaward-of-bridge berth area |
| Strong harbour current | Cape Hawke Harbour | Can make mooring, anchoring and berthing difficult | Plan current-relative approach, engine control and fendering |
| Limited yacht accommodation | Seaward of bridge | A safe bar crossing does not guarantee a berth | Obtain written or recorded confirmation before departure |
| Shallow water and shoaling | Harbour and Wallis Lake | Depth contours are indicative and change | Current local route, sounder, draft allowance and slow speed |
| Oyster leases | Wallis Lake | Submerged structures and narrow routes are hazardous | Do not enter inner lake without a separate plan and bridge clearance |
| Fatigue | Bar and mooring | Highest workload arrives after 8 to 12 hours | Rested helm and navigator for final two hours |
| Darkness | Departure or arrival | Islands, bomboras, bar and marks become harder to assess | Plan daylight bar arrival and night-capable departure team |
| GPS or AIS dependence | Entire route | User routes can cross dangers and not all traffic transmits AIS | Official charting, compass, visual navigation and independent checks |
